What is cardiac maker ?
Cardiac markers are used in the diagnosis and risk stratification of patients suffering from chest pain and suspected acute coronary syndrome (ACS). Cardiac troponins, in particular, have become the preferred cardiac markers for patients with ACS.
It appears in your blood if you are suffering from heart injury because your blood supply has been restricted. It might be due to the fact that you've had a heart attack. Other reasons can contribute to these levels as well. The levels of biomarkers are often used to quickly determine the severity of a heart attack.
What are types of Cardiac maker ?
1) Cardiac troponin :-This protein is much more widely used as a biomarker is known to be the most sensitive It enters the bloodstream within minutes of a heart attack. In addition, it is known to stay in your bloodstream for several days after all other biomarkers return to normal. Two tropics can be identified:
- Tropon T
- Tropon I.
Tropon I is more specific to the heart, thus remaining longer in the body is tropon I. Current AHA guidelines recommend the cardiac troponin as the best method for detecting a heart attack, using other biomarkers such as CK, CKMB and Myoglobin.
2) Myoglobin:- This protein sequesters oxygen. It is occasionally measured. To assist in the diagnosis of a heart attack, myoglobin may be added to Cardiac troponin. It is also not accurate for the diagnosis of a heart attack.
3) Creatinine kinase (CK):- CK is not very specific because CK levels can rise in many other conditions besides a heart attack.
This enzyme may also be measured several times over a 24-hour period. It will often at least double if you have a heart attack.
4) CK – MB:- CK-MB is a subtype of ck. CK with MB is more sensitive to heart damage from a heart attack. CK-MB increases 4 to 6 hours after a heart attack. But it's generally back to normal in a day or two. Because of this, it's not helpful if a health care provider is trying to figure out if your recent chest pain was a heart attack.
